I have the VT30 and love it. Still waiting to get a calibration. TBH, the biggest issue is that my room doesn't have window coverings because I mostly watch this set at night. I don't think calibrators want to start work at 10 PM...
I have light colored curtains. Most of my watching is evening with no light. When there is light, I throw a blanket over the window. One of my next steps will be to replace the curtains with something that blocks light.
Here's a thought for you. When the daytime calibrator arrives, have the 2 of you move the TV into a darkened room. When he's done, move the TV back to where it was.
